Expert Solution & Answer
Explanation of Solution
The enethiol is also the enol form which contains Sulphur molecule instead of Oxygen. The enethiol form is the alcoholic form of the Sulphur. The double bonded Sulphur is converted to thiol form of the Sulphur.
The enethiol form of 6-mercaptopurine is
The enethiol form of 6-thioguanine is

A pioneer in designing and synthesizing antimetabolites that could destroy cancer cells
was George Hitchings at the Burroughs Wellcome Company. In 1942, he initiated a pro-
gram to discover DNA antimetabolites, and in 1948, he and Gertrude Elion synthesized
6-mercaptopurine, a successful drug for treating acute leukemia. Another DNA antime-
tabolite synthesized by Hutchings and Elion was 6-thioguanine. Hitchings and Elion along
with Sir James W. Black won the 1988 Nobel Prize in Physiology or Medicine for their
discoveries of "important principles of drug treatment." In each drug, the oxygen at carbon
6 of the parent molecule is replaced by divalent sulfur. Draw structural formulas for the
enethiol (the sulfur equivalent of an enol) forms of 6-mercaptopurine and 6-thioguanine.

Q23:
Dr. Alghe has just performed a restriction digest on DNA she extracted from her samples. She must now run her DNA out on a gel to separate the fragments based on size. To do this she must prepare a 1.1% agarose gel, where the percentage is determined as mass/vol.
How many grams of agarose must she add to 413 mL of buffer in order to arrive at the correct percentage? (answer to 2 decimals)
**Assume the dissolution of agarose will not alter the final volume of the solution**
